I was able to open an X windows emacs session using:
(require '[clojure.java.shell :as sh])
(sh/sh "emacs")
on my system. The REPL did not give another prompt until I quit that emacs
invocation. I was able to get another REPL prompt immediately using this:
(future (sh/sh "emacs"))
When I tried running the terminal version of emacs without using the X window
system, it gave a valid complaint like this:
user=> (sh/sh "emacs" "-nw")
{:exit 1, :out "", :err "emacs: standard input is not a tty\n"}
You can also specify the file name and line number where the cursor should
initially be placed like so:
(sh/sh "emacs" "+57" "foo.txt")
In case it matters what versions of things I am using, I was able to get
similar results above on both of the following systems:
Mac OS X 10.6.8 + Oracle/Apple JDK 1.6.0_37 + Leiningen 2.0.0 + Clojure
1.5.0-RC2
Ubuntu 11.10 32-bit desktop + Oracle JDK 1.6.0_38 + Leiningen 2.0.0 + Clojure
1.5.0-RC4
I also tried it with Clojure 1.4.0 with the same good results.
